血液样本、血痕样本采样流程方法


现在这个年代做亲子鉴定,已经不需要抽血了,除非是做无创的才要去抽血,那么我们血液样本应该怎么去采集呢,以下就由本中心来为大家介绍;


血液样本采集程序:

1、相对于自己采集样本,采血液建议由相关专业的医护人员来采集,或者直接到本中心采集,只需要3-5滴即可哦,现在都是用自动针扎手指,再用血卡采集即可。

2、如果是自己采集的,需要邮寄的时候记得写上样本人员姓名,联系方式,地址等相关信息;

3、司法亲子鉴定必须到现场采集血液样本。

注意事项:

1、如果是用来做无创鉴定的,需要本中心寄送专业的血液EDTA抗凝管进行采集;

2、如果是在天热的时候寄送需要拿泡沫箱或者保温瓶加冰寄送;

3、采好的样本需要独立存放并且做好相应记号;

4、如果是在一年内有输过别人的血液或者骨髓移植,是不能做的想您可以选择其他样本例如,头发,指甲,口腔拭子等;


司法亲子鉴定的样本血痕采样流程

1、采血痕之前,先准备好,一次性的采血针,医用棉签,一次性医用手套,采样卡(以上都可以在药店买哦,或者直接咨询到本中心采样)

2、采样专员带好手套,用酒精棉签,在手指上面消毒,等待手指头自然干后,用专用的采血针轻轻的刺穿手指表面。

3、等待血液流出后用血卡采集3-5滴即可;

4、样本才好后在血卡信封写好样本人员归属姓名身份。

注意事项:血痕样本,可以保存的时间相对其他样本比较长,一般在阴干的情况下可保存1个月以上,但是如果放置时间过长还是会出现DNA降解现象,采完后尽早寄送到检测中心为佳。



Blood sample and bloodstain sample sampling process


Now in this era, it is no longer necessary to draw blood for paternity testing. Unless it is non-invasive, we need to draw blood. How should we collect blood samples? The following is an introduction from our center;


Blood sample collection procedure:


1. Relative to their own collection of samples, it is recommended to collect blood by the relevant professional medical staff, or directly to the center for collection, only 3-5 drops can be required. Now, automatic needles are used to prick fingers, and then blood cards are used to collect blood.


2. If it is collected by yourself, please remember to write down the name, contact information, address and other relevant information of the sample personnel when mailing;


3. Blood samples must be collected at the scene for forensic paternity testing.


matters needing attention:


1. If it is used for noninvasive identification, we need to send professional blood EDTA anticoagulant tube for collection;


2, if it is hot in the day, you need to send a foam box or thermos bottle with ice.


3. The collected samples should be stored independently and marked accordingly;


4. If you have blood transfusion or bone marrow transplantation within one year, you can choose other samples, such as hair, nails, oral swabs, etc;


Blood stain sampling process for forensic paternity testing:


1. Before collecting blood stains, prepare disposable blood collection needles, medical cotton swabs, disposable medical gloves, and sampling cards (all of the above can be purchased in pharmacies, or directly consult the center for sampling)


2. The sampling specialist should wear gloves, disinfect the fingers with alcohol swab, wait for the fingers to dry naturally, and then gently pierce the finger surface with a special blood sampling needle.


3. After waiting for the blood to flow out, use the blood card to collect 3-5 drops;


4. After the sample is ready, write the name and identity of the sample personnel in the blood card envelope.


Note: bloodstain samples can be stored for a longer time than other samples. Generally, they can be stored for more than one month under the condition of dry in the shade. However, if the storage time is too long, DNA degradation will occur. It is better to send the samples to the testing center as soon as possible after collection.
